Attack Vector: Local
Attack Complexity: Low
Privileges Required: Low
User Interaction: None
Scope: Unchanged
Confidentiality: High
Integrity: None
Availability: None

Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Local: The vulnerable component is not bound to the network stack and the attacker’s path is via read/write/execute capabilities. Either: the attacker exploits the vulnerability by accessing the target system locally (e.g., keyboard, console), or remotely (e.g., SSH); or the attacker relies on User Interaction by another person to perform actions required to exploit the vulnerability (e.g., tricking a legitimate user into opening a malicious document).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: Low: The attacker is authorized with (i.e., requires) privileges that provide basic user capabilities that could normally affect only settings and files owned by a user. Alternatively, an attacker with Low privileges may have the ability to cause an impact only to non-sensitive resources.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 2026-10-25.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

What to do

AI-suggested

1. Immediate mitigation should focus on upgrading Trend Micro Security (Consumer) to the latest available version beyond 17.7.1383, as vendors typically release patches for such vulnerabilities. 2. Restrict local access to endpoints running the affected software by enforcing strict access controls, limiting administrative privileges, and using endpoint management tools to monitor and control user activities. 3. Employ application whitelisting and endpoint detection and response (EDR) solutions to detect anomalous behavior that could indicate exploitation attempts. 4. Conduct regular memory scanning and forensic analysis on critical endpoints to detect potential information leakage or crashes related to this vulnerability. 5. Educate users about the risks of local privilege escalation and enforce strong authentication mechanisms to reduce the likelihood of unauthorized local access. 6. In environments where consumer-grade security products are used, consider migrating to enterprise-grade endpoint protection solutions that may have more robust security controls and faster patch cycles. 7. Implement network segmentation to limit the impact of any compromise resulting from this vulnerability, preventing lateral movement. 8. Maintain up-to-date backups and incident response plans to quickly recover from any potential exploitation that leads to system instability or data compromise.

Description

Trend Micro Security 2021 and 2022 (Consumer) is vulnerable to an Out-Of-Bounds Read Information Disclosure Vulnerability that could allow an attacker to read sensitive information from other memory locations and cause a crash on an affected machine. This vulnerability is similar to, but not the same as CVE-2022-35234.

Impact

For European organizations, the impact of CVE-2022-37347 depends largely on the deployment of Trend Micro Security (Consumer) products within their environment, particularly on endpoints used by employees or contractors. Although this vulnerability requires local access and low privileges, it could be exploited by insiders or through compromised user accounts to extract sensitive information from memory, potentially exposing credentials, tokens, or other confidential data. This could facilitate lateral movement within networks or escalation of privileges. The lack of requirement for user interaction increases the risk in environments where attackers have gained initial footholds. While the vulnerability does not directly affect availability or integrity, the potential confidentiality breach could undermine trust in endpoint security solutions and lead to data leakage incidents. European organizations with remote or hybrid workforces using consumer-grade security products may be particularly exposed if these products are not updated. Additionally, sectors with high data sensitivity such as finance, healthcare, and government could face increased risks if attackers leverage this vulnerability to access sensitive information. The absence of known exploits in the wild reduces immediate risk but does not eliminate the threat, especially as attackers often develop exploits post-disclosure. Therefore, European organizations should consider this vulnerability in their endpoint security risk assessments and patch management strategies.
